MACHINE FOR TENTERING,STRAIGHTENING, AND FINISHING WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 416,343, dated December 3, 1889.

I Application filed June 30, 1884. Serial No. 136,340. (No model.)

- To all whom it mayconcern:

view of parts shown in Fig. 9.

Be it known that I, ISAAC E. PALMER, of Middletown, in' the county of Middlesex and State of Connecticut, have invented a certain new and useful Improvement in Machines for Tentering, Straightening, and Finishing Woven Fabrics, of which the following is .a specification.

I will describe in detail a machine embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figurel is a side View of a machine wherein the fabric is stretched by diverging selvage-carrying wheels or rotary rims, the drawing including only a single drying-cylinder, and also including a spreading mechanism, through which the fabric is conducted to the selvage-carrying wheels or rims. Fig. 2 is a front elevation of the machine, the spreader mechanism being removed to illustrate more clearly the ma chine proper. Fig. 3 is a plan of the machine, including the spreader mechanism. Fig. 4 is a partial side view and vertical section in the plane of rotation of one of the selvage-carrying rims, and wherein are located the trunnions on which the selvage-carrying rims oscillate. Fig. 4* is a horizontal section on the dotted line y y, Fig. 4. Fig. 5 isa partly-sectional view on the dotted line at 00, Fig. 4. Fig. 6 is a sectional View of a part of the machine, very similar to Fig. 5, but having the trunnions on which the wheel or rim oscillates at one side ofthe plane of rotation, so that at the points of feeding and delivery the selvages of the fabric will have a slight reciprocating movement. Fig. 7 designates a transverse section of a delivery-roller and a portion of a pivoted frame to be used therewith in the example of my invention shown in Fig. 6. Fig. 8 is a plan of such roller and its supports. Fig. 9 is a detail view illustrating means whereby the trunnion-centers on which the selvage wheels or rims oscillate can be adjusted into the plane of rotation, or more or less out therefrom. Fig. 10 is a sectional Fig. 11 is a plan of such parts of a long endless chain machine as embody my invention; and Fig. 12 is a transverse vertical section on the dotted line 2 2, Fig. 11, with parts in elevation.

Similar letters of reference design ate corresponding parts in all the figures.

I will first describe the machine shown by Figs. 1 to 5, all inclusive.

A designates the bed or shears of the machine, which is supported by leg frames or stands A, and which is provided at the top with gibbed ways a, whereon are fitted two base-plates B B, which are capable of sliding thereon toward and from each other.

The base-plates B B are slightly rabbeted at to fit the outer edges of the ways, and are provided with pins at, having beveled faces which catch under the beveled edges of the guides or ways a, and so pre vent rising movement of the said base-plates. The said base-plates B B are moved toward and from each other by means of a screw-shaft B which may be turned by a crank b at either end, and which is mounted in bearings b. On the screw-shaft B are right and left hand threads which engage with nuts 19 on the base-plates B B, as best shown in Fig. 2, and thereby the two base-plates and the superposed mechanism may be moved toward and from each other to operate upon goods of greater or less width.

Upon each base-plate B B is an upwardlyprojecting pivot or fulcrum which in this instance is near the front of the machine, and upon this pivot is fulcrumed a frame plate or carriage C, constructed with an eye or hub b fitting the pivot and capable of swinging upon said pivot in a horizontal plane, as more fully hereinafter described.

Each frame or carriage C has mounted upon it a selvage-carrying wheel or rim, which in this example of my invention has not only a progressive rotary motion, but also an oscillating or vibrating motion in a direction transverse to its plane of rotation. The selvage-carrying wheels or rims might be provided with card clothing or tenter-pins to hold the selvages of the fabric-as, for instance, as shown in my Reissued Letters Patent No. 8,978, dated November 25, 1879; but I deem it most desirable to employ in connection with them belts or moving bands, which hold the selvages upon them and have a progressive movement encircling about half the periphery of the rims.

A detailed description of the selvage-earrying devices will best be understood by reference to Figs. 1, 4, and 5.

Each wheel or rim 0 has an inwardly-projecting annular flange or web 0*, to whichare bolted a number of sections 0, forming a complete ring having a rounded groove or channel 0 in its inner periphery. The parts 0 c constitute the only rotary parts of the wheel or rim, and are supported while rot-at in g by a number of shoes or stationary blocks 0, which are here shown as three in number for each rim. The shoes or blocks 0 are each held between a pair of jaws 0 0 which are hinged ate, and which may be tightened upon the interposed shoe by a bolt 0 The clamping-jaws are secured by the bolt (3 to the outwardly-projecting annular flange or web 0 of a center frame or ring D, which is non-rotary and is of T shape in transverse section.

Upon the carriage or frame C, inside of and outside of the center frame D, are erected standards (I, which are divided to accommodate the rim 0, and which are received in notches 0 at diametrically-opposite points in the center frame, and at these points the center frame is supported by trunnions d, which may consist of screws fixed adjustably in the cross portions of the standards 01, and

entering sockets or bearings formed in the center frame D, as best shown in Fig. 4. From the foregoing it will be seen that the rim 0 may turn freely about the center frame D, and that the trunnions d constitute a support for the frame D, and consequently for the selvage-carrying devices, which is maintained against lateral reciprocation and which provides for the oscillation or vibration of the frame D and the rim c. It will further be seen, by reference more particularly to Fig. 4, that the supports for the frame D are arranged near the feed and delivery points for the fabric 3, and that consequently little or no reciprocation of the fabric occurs at these points, whereby the fabric is caused to be fed to and delivered from the machine in approximately straight lines.

Although the means for supporting the selvage-carrying rims c is very desirable, I do not confine myself thereto, as other constructions and arrangements of supports may be employed to a like end.

In connection with each carrying-rim c, I employ an endless band e, which is mounted on pulleys or wheels 6' e e 6 and encircles or embraces about half the circumference of the rim c. In the rim 0 is a concave seator half-round circumferential groove 0 and on that face of the belt or band a which comes next to the rim are teeth or projections which fill said groove snugly. These teeth or projeetions may consist of small pieces of brass having prongs, roots, or spurs which are driven through the belt or band and clinched. The pulleys or wheels e e for the band a are here shown as journaled upon brackets e e, which are bolted to and oscillate or vibrate with the center frame D and rim 0; and the two pulleys c e constitute idler-pulleys and may be moved to tighten the belt or hand. To the upper part of the center frame D is bolted a plate or forked upright 0 and e designates a double bracket or frame which is fitted to slide up and down in the fork of the plate or upright e", and has its two diverging branches 6 e mortised at 6* to fit and receive through them the straight portions of the forked plates 6'. The two branches of the double bracket 6 carry the idler or tension pulleys 6 c and may be raised by a screw a to put tension 011 the belt or band 6. The end of the adjustingscrew 0 issquare, to provide for applying a wrench, and a collar c thereon rests against a lug or car c on the plate c, and forms a thrust-bearing. The same bracket 6'' which carries or supports the pulley or wheel 6 also supports a second wheel or pulley e on the shaft of which is a pinion e gearing with a pinion e on the same shaft with the pulley e", and thus rotary motion imparted to the pulleys c by means hereinafter described, transmitted to the pulley c and a progressive motion is given the band 6.

At each end of the bed A are a pair of uprights or standards f f which are braced and connected by cross-rods 7 To the two uprights or standards f at the front of the machine is journaled a feed-roll or a roll f under which the fabric 5' passes to the machine, and said roll is composed of short sections capable of turning independently of each other on acommon shaft or rod. To the standards f at the back of the machine, is journaled a delivery-roll D, under which the fabric passes, and is delivered to a drying-cylinder E, which may be the first of a series. The cylinder E, or series of cylinders, constitute fabric-carrying devices, whereby the fabric is held extended during drying, and which are supported so as to preserve and produce the direct travel of the fabric in a straight line during the latter portion of its movement through the machine. This drying-cylinder and the remainder of the series (not shown) may be heated by steam introduced through its journals or in any other suitable way, and the construction and arrangement of such cylinders are well understood by persons skilled in the art. As here shown, the cylinder is rotated bya pinion and gear wheel f f from a shaft f, to which rotary motion is imparted by a belt f" from the driving-shaft f which is journaled in the end or leg frames A.

The fabric 3 maybe spread out by the feeders or attendants standing at the two selvagecarrying rims 0; but I deem it desirable to subject it to a preliminary opening or spreading operation while on its way to the attendants, because it relieves them of a considerable amount of work and leaves them to give ITO ITS

work more perfectly.

I have here represented a spreading mechanism which comprises two shafts or bars f 8 f grooved or ribbed spirally throughout their length, and having reversed pitch from the middle of their length'toward opposite ends. The bar or shaft f is journaled in swinging frames f fulcrumed at f 11 in standards f and having an adjustable connection with said standards consisting of a curved or.slotted'arm f and a cla1nping-screw f spreading rod or shaft f is carried in swinging frames f fulcrumed at f 16 to the standards f, and made adjustable by means of a curved and slotted arm f 17 and clampingscrew f or other suitable means. In the standards f is journaled a sectional roller f composed of short roll-sections capable of turning independently of each other upon a common rod or shaft. The. fabric 3 is carried over the sectional roller f under the spreading rod or shaft f and then over the spreading rod or shaft f and under the sectional roller f and to the selvage-carrying rims c. The two spreading rods or shafts are connected by a belt f 19 and pulleys f so that the rotation of both rods or shafts is insured.

Beneath the pivots b and near the front of the machine, are two shafts F F, on which are reversely set cone-pulleys g g, and which are rotated by belts g g, driven from reversed cones g g on the driving-shaft f These belts g are crossed so as to bring both driving portions of the belt on the pulleys g g onthe under sides thereof, and each belt is controlled by a shipper 9 which is attached to a frame adapted to slide along a rod or fixed bar g and having a spur-rack g Upon a rod 9 extending lengthwise of the machine are two frames g each comprising bearings for a belt-shifting shaft g on the inner end of which is a pinion g engaging with the rack 9 and on the other end of which is a foot-roll g whereby the shaft may be turned to move the shippers g ,.and thereby to shift the belts g to drive one shaftF to a variable degree faster or slower than the other shaft F. Each shaft F is mounted in a bearing 9 depending from the bed A, and is held against longitudinal movement by a collar g* on one side of this hearing and the cone-pulley g on the other side thereof. From each base-plate B B depends a bearing g, which may move along the shaft, and in which is fitted the sleeve or hub of a pulley 9 This hub or sleeve g rotates freely in the bearing g and is conlined against longitudinal movement in its bearing, and is engaged by a groove and a feather with the shaft F, so that it can slide along the shaft, but will always turn therewith. From the hub or eye b of each horizontal swinging frame or carriage there extends upward a standard h, on which are idler-pulleys h h, and h designates an endless driving-belt which encircles the pulley g, and is deflected and properly directed by the idlers h onto the pulley e from which rotary motion is transmitted to the pulley c and thereby to the band or clamping-belt e, which confines the selvage on the rim 0.

From the above description it will be understoo'd that the swinging of the frames or carriages 0 upon their pivots 17 provides for the adjustment of the selvage-carrying rims at different angles of divergence; but when the carriages are thus adjusted the plane of rotation of the idler-pulleys h is correspondingly changed, owing to their standards hbeing carried by the frames or carriages C, and hence the belts It will deflect over them properly. The distance between the pulleys g and idlers h is sufficient to enable the belts 71 to adjust themselves to their pulleys.

When the center frame D and the selvage-carryin g rims c are oscillated or vibrated to and fro, the bands 2 and their supporting and driving pulleys all move with the center frame D; but the angle formed by the planes of rotation of the pulley e and idlerpulleys h is so slight that the length of belt 71 between them compensates readily for such differences. In this example of my invention the two selvage-carrying rims 0 receive rotary motion from the engagement of the bands e with them; but it is not absolutely necessary to employ separate driving mechanism for the two bands, as here shown, although I deem it preferable, as then the movement of either selvage of the fabric may be increased or retarded relatively to the speed of the other. If for any reason such adjustment or variation of speed were not deemed of importance, a single long shaft could be substituted for the two shorter shafts'F, and this long shaft might be driven from the drivingshaft f by a single belt and cone-pulleys. In machines of this class it is customary to employ a stationary frame or drag between the selvage-carrying wheels or rims to support the body of the fabric. A drag or frame of any ordinary or suitable descriptionmay be used; but as I here make no claim thereto I have shown a drag of very simple form,which I will now describe.

Gdesignates a standard erected on the bed A at the middle of its length and having an arched top, and upon the standards (I, erected on each carriage O, are secured arches or frames G. The bars G2 of the drag are made in sections, and such sections are capable of sliding one on another to permit of the selvage-carrying rims being adjusted at different angles of divergence and to different distances apart. At the point where the sectional bars G lap they are supported by the arched top of the standard G.

In lieu of the drag described, which is stationary, any description of stationary or movable drag or supporting-frame may be used.

I will now describe how a uniform tension and lateral stretchingis produced in the fabric, even though the width of the fabric is not uniform, or in case of the same width of selvage not being always fed between the bands (2 and the rims c. I employ balancing devices, which are shown as consisting of springs ll, bent nearly into the form of a circle and placed around the eyes or hubs U of the carriages or laterallyswinging frames C, as best shown in Figs. 1, 2, 4, and 4*. One end 7&3 of each spring is secured fast to the base-plate B or B by a pin or bolt, and the other end isadjustably secured by a thumb-screw 71.4 to the web of the carriage orswingin g frame 0. \Vhcn applied as shown, the springs exert a constant tendency to draw or move the two selvage-carrying rims or wheels away from each other by swinging the two frames orcarriages C in opposite directions; but such movement or increase of divergence of the wheels or lllllS is resisted by the fabric which is between the two. The lateral pull of the fabric and the tension of the springs therefore form two opposing forces, and the latter of these forces yields to the former and allows the wheels or rims to move slightly toward each other when the fabric between the wheels decreases slightly in width. At the delivery side of the rims or wheels each carriage U is furnished with a pinion i, which is provided with a hand-wheel 5, whereby it maybe turned, and which gears into a short rack 21 formed upon or attached to the base-plate I3 or B. The journal for the pinion i is formed by a screw "i which fits a screw-threaded socket Win the said carriage C, and may be turned by a handle i as best shown in Fig. 4.

\Vhen the carriage is to be left free for selfadjustment, as above described, the screw 1' is left slack enough, so that the pinion i may freely turn on it, and as the carriage swings on its pivot b the pinion 1' runs along the rack i and rotates. When it is required to prevent such self-adjustment of the carriage, the screw 11 is tightened up and clamps the pinion between its head and the carriage and thusprevents the turning of the pinion. The locking of the pinion in the rack prevents the carriage from moving on its pivot Z).

I have before described generally how I produce a lateral change in the direction of movement of the fabric, but such change will be more readily understood by reference to Fig. 3. As in other machines of this class, the drying-cylinder E and the feeding and delivery rolls f D are all substantially parallel. In prior machines of this class the selvage-carrying wheels or rims have been set inclined in opposite directions relatively to a line drawn at right angles to the dryingcylinder.

In Fig. 3 I have represented the selvagecarryingwheel or rim which is upon the baseplate B as inclined very slightly toward the left from a line drawn at right angles to the drying-cylinder, and the other wheel or rim, which is upon the other base-plate B, inclined To effect this result,

similarly, but in a far greater degree, thereby securin g the divergence necessary to stretch the fabric properly. The fabric may be said to be given its first direction as it passes under the feed-roll f at the feeding-point, such direction being directly at right angles to the dryirig-cylinder. As the fabric is grasped by the selvage-carryin g wheels or rims, its direction is shifted or diverted laterally toward the left, and as the fabric passes under the delivery-roll D and onto the drying-cylinder its direction is again changed or restored to a direction at right angles to the cylinder and the fabric retains its straight direction of travel throughout its passage over the dryingcylinders. Y

I have before stated that the result is greatly enhanced by reciprocating or vibrating the fabric laterally, and will now describe one means of accomplishing this result, reference being made more particularly to Figs. 1, 2, 4, and 5.

As before stated, the frame or body D of each selvage-carrying rim 0 is capable of oseillating on the trunnions (l and imparting such a motion to the rotating rim 0. Secured fast to each base-plate I3 15 is a standard j, forked or bifurcated at the top and having fulcrumed or pivoted to it at its upper end j a lever 7.", which extends outward and is capablc of rising and falling motion upon the pivot j as a center. To the upper and lower portions of the body or frame I) is pivoted at 3" a bail or yoke I, receiving through a socket or eye j the lever 70. To the outer end of each lever 7a is universally connected a pitman or eccentric rod 7o, at the lower end of which is an eccentric-strap fitting an eccentricl on a shaft J. The shaft J is rotated by any suitable gearing as, for example, by spurwhcels Z Z on the shafts J f and an idlerwheel Zand the two eccentrics should be set at diamelrically-opposite points. As here shown, each eccentric 1 contains an inner adj ustable section Z*, whereby the throw of the eccentrics may be varied. As shown in Fig. 4, the section Z* may be rotated within the eccentric Z, and may be secured in any position to which it may be adjusted by means of a key engaging semicircular grooves in the eccentric and the adjustable section. (Shown more clearly in Figs. 4 and 5.) The shaft J is longitudinally grooved and the eccentrics are connected therewith by feathers, so that they may move along the shaft as the baseplates B B are moved toward or from each other. As the shaft J rotates, the levers 7c impart an oscillating or vibrating movement, through the bails I, to the center frames or bodies D in a direction at right angles to the plane of rotation of the selvage-carrying rims c, and the fabric thus receives a lateral reciprocating or vibrating movement between the points of feed and delivery during its progressive movement. When the centers of the trunnions d which constitute the centers of oscillation of the frames D and selvage-carrying rims, lie in the same vertical plane as said rims, the points of feed and delivery of the fabric which are in the prolongation of the axes of the trunnions will be stationary; but by placing the center of the trunnions outside the planes of the selvage: rims the fabric may be given a reciprocating movement at the selvages alternately not opposite or in the same vertical plane ery points.

with the circumferential groove or seat 0 therein, but is nearer the middle of the machine, and consequently the rising and falling movement of the lever kwill oscillate the rim and will produce a rising and falling movement at the'points of feeding and delivery. The delivery-roll D is here shown as journaled in opposite ends of a frame D which is pivoted by a bolt m at about the middle of its length to a bar or stretcher D extending between the uprights or standards f. The roll-frame D can oscillate on its pivot m to allow the ends of the roll to rise and fall alternately. In order to prevent undue rising movement of either end of the roll-frame D I provide the stretcher or" rail D with guards or abutments m, which extend over the end portions of the roll-frame D and form stops thereto.

In some cases it may be desirable to provide a machine which can be adjusted to produce a simple lateral reciprocation of the fabric, or such movement, and, in addition thereto, a reciprocation of the selvages alternately in reverse directions at or near the feed and delivery points. I have shown in Figs. 9 and 10 an example of trunnion-beau ing whereby such adjustment may be effected. In the standard dand center frame D are formed cylindric sockets or holes 71. n, wherein are fitted plugs or sleeves n n These plugs or sleeves can be adjusted circumferentially and held by set-screws n* against shifting. They are connected by a trunnionpin d, as shown in Fig. 10, which forms the center of oscillation and is eccentric to the sleeves or plugs n 11 WVhen the parts are adjusted to the position shown in Fig. 10, the trunnion d is in the plane of rotation of the selvage-carrying rim 0, and an oscillating movement of the rim will not produce any rising and falling of the feeding and deliv- VVhen' the plugs or sleeves n n are turned half round and there secured, the trunnion (1 will be to the left of the plane of rotation of the selvage-carrying rim 0, and

consequently an oscillating movement thereof will produce also a rising. and falling of the points of feed and delivery and an alternate and longitudinal reciprocation of the selvages.

Figs. 11 and 12 represent only such parts of a chain-machine as are necessary to illustrate my invention. K K designate endless chains or bands, which may be provided with tenter pins or nippers for grasping or holding the selvages of a fabric. These chains or bands are driven by wheels 0 0 911 a shaft 0. The chains or bands K are guided by tracks or ways, constituting supports, here shown as composed of sections L L, L L, and L L The sections L L are divergent, and by them the stretching and bringing of the fabric,to full width is effected. The sections L L and L L are parallel. At the feeding end of the machine are idlers p p for the chains, supported in hearings on the sections L. The sections L L L of the tracks or guides are pivotally connected at their ends to cross-bars L L L and the cross-bars L L are pivoted at q to posts or other supports q. The crossbar L is capable of being reciprocated by a connecting-rod and crank r r. The rod 1' is pivotally connected with the cross-bar L and has an extensive bearing-surface r on a column M. The crank r is on a vertical shaft r which is supported by an extension m of a column m, and rotated by bevel-wheels r from a horizontal shaft 1 A section L of the track or guide has a projection or arm r connected by a rod 7 with the crank r, and hence it will be seen that the crank r imparts both a lateral reciprocation and alongitudinal reciprocation to the tracks or guides.

It will be understood that the sections L L, or analogous sections of guides at or near the entering end of the machine, are alone recip-' rocated laterally, and that the sections L and other sections nearer the delivery, end of the machine, are held so as to preserve the straight run or travel of the fabric.

For driving the shaft 0 it is necessary to employ mechanism which will permit the shaft to swing slightly as the tracks or guides are reciprocated longitudinally. Such mechanism is common in machines of this class.

It will be seen that the bars L L constitute supports for the supports L L, and are maintained against lateral reciprocation, and, through the pivotal connection therewith of the supports L L, admit of the lateral reciprocation of the latter. The supports L L being at the feed and delivery points for the fabric to and from the laterally-reciprocating supports L L, there will be little or no reciprocation of the fabric at the feed or delivery points, but the same will be fed and delivered in approximately straight lines.

I have here shown a vertical shaft 0 geared by bevel-wheels 0 with the shaft 0 and receiving motion by bevel-wheels 0 from a shaft 0 The shafts 0 and 0 have bearings in a standard 0 and on the upper por ion thereof is fitted a yoke or frame 0 which is capable of swinging freely, and in which are provided bearings 0* for the shaft 0. The center of oscillation of the shaft 0 is therefore concentric with the vertical shaft 0 By means of the crank and connecting-rods the fabric, which is carried by the chains through the lateral]y-reciprocating guides, tracks, or ways, will be subjected to a lateral reciprocating or vibratory movement and a longitudinal reciprocation of the selvages during its forward and progressive movement, and therefore has its direction of movement changed laterally.

In Fig. 5 I have represented the selvagecarrylng rims c as at the middle of their vibrating or oscillating movement, the two eccentrics I being at half-stroke. If desired, the shaft J may be stopped when the eccentrics are at opposite ends of their stroke, and their rims 0 will then be held in inclined positions in planes coincident with their axes of rotation, both rims being canted or inclined in the same direction from the perpendicular. If held in such inclined or canted positions, it is obvious that another lateral change in the direction of movement of the fabric would be produced between the points of feed and delivery. This would be true even if the rims 0 were set equally divergent in opposite directions from a center line at right angles to the drying-cylinder, and were also set canting or inclined vertically, as above described. It is advantageous to employ the selvage-carryin g rims provided with circumferential grooves and bands having projections entering said grooves, because then the fabric is held more firmly with a bite upon a less width of selvage, and the band and selvage are prevented from slipping laterally off the said rim. I have here represented the selvage-carryin g rims as receiving rotary motion through the progressive motion of the bands 6, but in some cases the rims and bands may have no movement of themselves and be left free to be moved by the pull or drag of the fabric as it is drawn forward by the drying-cylinder. l

I may, if desired, provide the selvage-carrying rims each with a circumferentialrib or pro ection in lieu of a groove, and in such use the bands 6 would each have a groove fitting such rib or projection.

What I claim as my invention, and desire to secure by Letters Patent, is-
